If you want to be able to recognise them, my dear brethren, you must ask the Holy Ghost for His light. He alone will give you this grace. No one could, with impunity, point out these sins to you; you would not wish to agree nor to accept them; you would always find something which would convince you that you had made no mistake in thinking and acting in the way you did. Do you know yet what will help to make you know the state of your soul and to uncover this evil sin hidden in the secret recesses of your heart? It is humility. Just as pride will hide it from you, so will humility reveal it to you.
From St. Francis de Sales’ Introduction to the Devout Life CHAPTER IV.
OF EXTERIOR HUMILITY.
